Sensor arrangement with RFID
A grommet ( 20, 30 ) as part of a fastening element for a building envelope essentially comprises a head ( 21 ), a tip ( 22 ) and a sleeve ( 23 ) therebetween, wherein the head ( 21 ) is essentially constructed as an extensive washer ( 24 ), the central hole of which is adjoined by the tubular sleeve ( 23 ). The tip ( 22 ) narrows essentially in a conical or tapered manner to a smaller diameter. The grommet ( 20, 30 ) has a sensor arrangement ( 25 ), with at least one RFID transponder with antenna and a sensor operatively connected to the transponder.
1. A combined grommet and sensor arrangement,
the sensor arrangement comprising:
an RFID transponder with antenna, and
at least one sensor operatively connected to the RFID transponder;
the grommet comprising:
a head with a washer,
a sleeve, and
a tip;
the RFID transponder with antenna and the at least one sensor are arranged in a spatially distributed flat manner;
the RFID transponder with antenna is located on the sleeve or on the washer;
and the sensor is arranged on the sleeve closer to the tip than the RFID transponder or on the tip such that the sensor is introducible at a defined installation position and depth in a layer of a roof structure.
2. The arrangement according to claim 1 , wherein the grommet is a plug-in element with a closed tip.
3. The arrangement according to claim 1 , wherein the grommet is a fastening element with a tip including a through opening adapted to receive a fastener.
4. The arrangement according to claim 3 , wherein the through opening is coaxial to a central axis of the sleeve.
5. The arrangement according to claim 1 , wherein the tip of the tubular sleeve of the grommet narrows in an essentially conical or tapered manner from a sleeve diameter to a smaller diameter.
6. The arrangement according to claim 1 , wherein the fastening element is adapted to fasten insulation layers on a fixed substructure.
